I will be running 300mm wilwood 4 pots up front and 2wd cossie calipers and discs on the back of my series 2, will I need to use an after market compensator valve?
Cheers

 

i beleive so. ive heard the improved discs on the rear can lock up under heavy braking.

 

leave the drums on

 

Its gonna be running just over 300hp with the occasional track day, although I know the standard drums are not too bad

 

Fuck it let's put drums on the front too

I've got a bias valve wouldn't say its essential but does mean you can play with settings to see what works best!! Well worth what it costs I've got a compbrake one

 

Ask the people who smashed there cars up with rear discs and no bias valves if they think there essential or not.

And what is the point of fitting them only to dumb them down so they don't work aswell.

 

+1 rear discs not needed imo

 

As said before chaps gonna be over 300hp!
Will try and do some research on what the big power boys are running

 

best remove the old bias value from the rear brake first. When i did mine i replaced all the lines and fitted two master cylinders.

drum brakes are shit

 

Did you use copper lines or braided and run them into the vehicle to the compensator?
Got any pics pal?

 

drums look rubbish too

 

irrelivent. fact is with big powerfull stoppers up front your going to get more weight transfer to the front so the back end will go lighter under heavy braking which will mean the drums will find it easier to lock up never mind fitting discs!

 

That's true, so a bias valve is needed either way

 

If it's stripped out like mine you'll need bias valve just for the drum brakes! My cossie discs lock all the time and it's fooking dangerous even thou i got bias valve shut right down and grooved pads . If it's performance your after you'll just need 1.3 bonus drums. Back won't lock as easy so you can stamp on the pedal

 

are you still using the old pipes

 

How is everyone running there brake lines inside for the bias valve?

 

mine run inside but mine is a track car

if the brakes are done properly then they are not a problem imo

can only say on my experience and i can stamp on the pedal hard

 

Mine is track aswell gus, you have any pictures of how you have done yours?

 

i have a bias peddle box fitted now

no real pics as such as have changed peddle boxes

 

re make all the brake lines get rid of all the shity valves etc , run 1 line to the front and 1 line to the rear and put a bias valve in it and turn the rears rite down or the back will be coming round on u , some times even with drums the back comes round if its a light car

 

mine is still using the std valves as well as my bias valve and its still too much coz the back wheels can lift off ground when breaking hard coz its stripped out.
i got rst master cylinder, split both lines into two, joined one pipe from each together and through a (under bonnet) bias valve then into the std valves then out to the back brakes, so ive effectively got one joined system instead of the std split diagnal fl + rr and fr + rl braking system

 

Cheers stuart, is it worth putting the valve inside the car, or put it in the engine bay turn it down and leave it?

 

inside

 

I've just redone all mine like Stuart has said to do it. Mines not a track car and my brakes feel alot better

 

How did you run them through the bulk head to the inside and back out?

 

Apparently mots can be an issue with a single rear brake line I was told. Don't know exactly what reason
